But when I click on the Button this Listener is added to, the store update blocks the whole application and the mask is not being rendered (that is my subjective view).

The idea: this onclick method should change the Boolean "checked" on my BaseModel objects, which is rendered using a Checkbox column, this is very slow, so I want to display a mask and use the Disable event to disable all child elements.

Is this not possible in Java, but only in JS?
I would be really grateful for your help.

Good day.

more details about using mask() method

more details about using mask() method

could you demonstrate more details for using mask() method?
because when I used mask() method, it was not working.
for instance, a tabitem including a grid inside
when I override onRender method.
protected void onRender(Element parent, int index){
this.el().mask();
this.initGrid();// a method to initiate grid
//after initiating the grid
//unmask this tabitem
this.el().unmask()
}

// but it could not be working.
//so could you tell me more about these.
//thanks
